BYK Lectures at the European Coatings Show 2019

March 18 - European Coatings Conference

Due to the difference in surface tension between pigments and water, wetting and dispersing additives are being used to obtain good processability for water-borne coatings. Apart from pigment affine groups, these additives exhibit hydrophilic segments to facilitate the system compatibility and provide steric stabilization of pigments. As these components remain in the cured coating, they bear the risk to increase overall hydrophilicity and, thus influence certain coatings characteristics such as water, stain and corrosion resistance negatively. Therefore, wetting & dispersing additives are selected not only by their ability to ensure pigment stabilization but also by their ability to minimize detrimental effects on water sensitivity. This is especially important for anticorrosive primers, DTM coatings or wood coatings, where stain resistance is required. BYK has developed dispersing additives based on novel chemical structures, which combine sufficient viscosity reduction and deflocculation of inorganic pigments on one hand as well as least negative influence on water, stain and corrosion resistance on the other hand.

Nowadays, spray applications, such as HVLP, Airmix, and airless, are commonly used to apply water-based systems. This way of carrying out the application is always a challenge for defoamers since a lot of air is entrapped in the film, often as a result of the high pressure involved.
BYK has now completed its defoamer range with the latest development of BKY-1786. This family covers the whole spectrum of the properties required for defoamers used in spray-applied systems, from highly incompatible and most efficient products to efficient and less incompatible products. The range comprises 100% as well as emulsion-based products – and they all meet the latest formulation requirements for environmentally friendly coatings.

High-performance superplasticizers enable outstanding flow and workability properties in concrete applications. However, due to the foam-stabilizing effect of several PCE-based plasticizers, it is always possible that maximum strength properties might not be ultimately achieved in the end system. The use of defoamers is therefore mandatory in such formulations. Numerous defoamers currently in use are too incompatible and therefore cause phase separation in the concrete additive. Over a longer period of time, many defoamers also tend to become ineffective in the end system.
BYK will be showcasing BYK-1680, a novel, VOC-free liquid defoamer for PCE Admixtures and concrete applications. The new product is characterized by its excellent and long-lasting defoaming effect and very good compatibility in aqueous polymer solutions and building material formulations.

Speaker: Dr. Markus Möller
Head of Global End Use Construction

After completion of his studies in applied mineralogy, Dr. Markus Möller’s professional career initially began as product manager for a leading global manufacturer of construction products. He then transferred to a large specialty chemicals enterprise, where he took on various management functions in R&D and in the marketing and sales of rheological additives. Since October 2013, Dr. Möller has been Head of Construction Additives at BYK-Chemie.

For many years, conventional solvent-borne epoxy technologies dominated the protective coatings market. 
New VOC and local regulations, as well as customer demands, have changed the view of things. Water-borne epoxy primers and mid-coats have become highly interesting for the protective coatings market.
Established rheology additives are well known for their use in water-borne coatings, but unfortunately perform very differently in water-borne 2P epoxy coatings.

The new additive technology has been developed to overcome these existing challenges and to support an easy production process, with good storage stabilities, anti-settling properties, as well as improved sag resistance compared to common rheology additives. This presentation will not only provide an overview of the limitations experienced with existing rheology modifier technologies, but will also highlight a new rheology additive technology which allows water-borne epoxy systems to close the performance gap on traditional solvent-borne and solvent-free systems.

Speaker: Heiko Juckel
Global Head of End Use Marine & Protective Coatings

Before joining BYK-Chemie in 1993, Heiko Juckel studied chemistry and completed an MBA degree. He is the BYK contact for additives in the global marine and protective coatings market. His experience in the coatings industry over the past 25 years has made him a networker and a valuable partner for the branch, whether it be for new developments or for customer projects.

Increasing complexity, emerging regulations, and rising costs required to ensure global marketability – these are the top three aspects in regulatory affairs.
Constantly keeping pace with an ever-changing regulatory environment is challenging – but it does create opportunities to drive business forward, developing sustainable products that fit both technically and regulatory.
Within BYK, we monitor the regulatory trends very carefully to ensure a tailor-made service for our customers and their applications that make use of our additives.

Speaker: Carina Kraft
Head of Product Stewardship

Carina Kraft first came into contact with BYK while studying business chemistry at university. In 2012, she launched her professional career at BYK in the Regulatory Affairs team. Since May 2015, Ms Kraft has been responsible for the area of Product Stewardship, which deals with a variety of regulatory issues relating to additives.

Solvent-free, radiation-curable coating systems have been used in industry since the 1970s; however, they are gaining considerable importance globally as an alternative to conventional solvent-borne coating systems for the wood and furniture industry. Initially, radiation-curable coating systems were primarily formulated as high-gloss clear coat systems, but for some time now their development has tended towards deep-matt or pigmented formulations. A novel wetting and dispersing additive sets the highest standards for the dispersion and stabilization of inorganic and organic pigments in solvent-free radiation-curable wood and furniture coatings. A study across the pigment range has shown this solvent-free product to meet the highest technical requirements such as pronounced reduction in viscosity, improved development in color strength throughout the dispersion process, and high-quality coloristic properties.

While commonly used silicone surfactants for water-borne coatings tend to lose performance at increasing application speeds, BYK’s latest addition to its water-borne product portfolio provides not only efficient static but also highly dynamic surface tension reduction. As a result, this novel silicone surfactant called BYK-3456 simultaneously improves surface tension and eliminates surface defects such as poor leveling, orange peel, and roller marks – while any tendency to stabilize foam during production or application is kept to a minimum.

Many high-quality products involve multi-layer coatings: on plastics for mobile telephones, for example, or on metal coatings for automobiles. The surface tensions/energies of the different layers such as filler, base coat, and clear coat have to be well adjusted. Often this is challenging because coating layers come from different suppliers. Macromer-modified additives are able to control the surface energy of the applied coatings and inks, which positively affect both the wetting and the adhesion of the sequential layer.
